pfsoutjpeghdr(1)	    General Commands Manual	      pfsoutjpeghdr(1)

NAME
       pfsoutjpeghdr - Write images or frames in JPEG-HDR format

SYNOPSIS
       pfsoutjpeghdr  (<file> [--linear] [--quality <val>] [--correction <cor-
       rect>] [--frames	<range>])  [<file>...]

DESCRIPTION
       Use this	command	to write JPEG file with	HDR extension.	This  software
       makes  use  of  the  High Dynamic Range Imaging Library from Sunnybrook
       Technologies Inc. (c) Sunnybrook	Inc. 2005

OPTIONS
       --quality <val>,	-q <val>
	      The --quality setting controls the  overall  compression/quality
	      trade-off,  with	100  being  the	maximum	setting, producing the
	      lowest losses and	the largest output  files.   Quality  settings
	      below 70 may result in significant image degradation, and	should
	      be avoided in critical applications. Default: --quality=90

       --correction <correct>, -c <correct>
	      The --correction setting	controls  the  algorithm  used	during
	      downsampling  of	the HDR	ratio image data.  The default precor-
	      rect option compensates for resampling errors by	adjusting  the
	      tone-mapped  image  to  maximize the accuracy of the HDR result.
	      This option may sometimes	induce modest halo  artifacts  in  the
	      tone-mapped image	at lower quality settings.  If the tone-mapped
	      (backwards compatible) image is more important than the HDR ver-
	      sion, the	postcorrect option may be used,	instead.  To avoid all
	      artifacts	from HDR resampling, specify the fullsamp option. This
	      will  result  in slightly	larger image files. Default: --correc-
	      tion=precorrect

       --alpha <a>, -a <a>; --beta <b>,	-b <b>
	      The --alpha and --beta settings control color desaturation  dur-
	      ing tone-mapping,	which will also	permits	super-saturated	colors
	      to pass through safely.  (See the	appendix of the	paper by  Ward
	      and Simmons cited	below for details.) Use	--alpha	< 1 to desatu-
	      rate colors and --beta > 1 to enhance color saturation contrast.
	      Any  input  color	 space	will  be converted to the standard YCC
	      color space of JPEG, based on the	CCIR-709 (sRGB)	primaries. De-
	      fault: --alpha=1,	--beta=1.
